M ETHOD OF MAKING FENCE BARBS OF SHEET METAL.

SPECIFICATION forming part of Letters Patent No. 302,534, dated July 22,1884.

Application filed May 21, 1883 Renewed June '7, 1884. (No model.)

To all whom it may concern.-

Be it known that I, EDMUND JORDAN, a citizen of the United States, andresiding at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Method of Making Barbed MetallicFencing, of which the following is a specification.

My invention consists of slitting blank strips of fiat bar steel, so asto make projecting ribs at intervals along the edges of two strips intowhich the blank is separated, so that the ribs of one strip are to betaken from the spaces between the ribs of the other strips, which ribsare then slitted along the lines of the edges of the strips in thedepressions between the ribs, and then bent out to form the projectingbarbs, all as hereinafter fully described, reference being made to theaccompanying drawings, in which--.

Figural is a plan view of ablank strip slitted along the middle todivide it into two strips with projecting ribs along one edge to formbarbs, the form of the slit being that employed for ribs to make asingle barb. Fig. 2 is aplan View of a blank strip slitted along themiddle to divide it into two strips, with projecting ribs along one edgeto form barbs, the form of the slit being that employed for ribs to maketwo barbsone at each end of each rib. Fig. 3 is a plan view of one ofthe ribbed strips from the blank of Fig. 1, with the ribs slitted fromone end along the edge of the strip preparatory to bending them into theprojecting condition for barbs. Fig 4 is a plan view of one of theribbed strips from the blank of Fig. 2, with the ribs slit-ted from bothends along the edge of the strip preparatory to bending them into theprojecting position for making two barbs from one rib. Fig. 5 is an edgeview of the barbed strip of Fig. las it appears after slitting the barbsalong the edge of the strip, as in Fig. 3. Fig. 6 is a plan view A andcrosssec'tion of the completed barbed strip from the blank of Fig. 1.Fig. 7 is a plan view and cross-section of the completcd barbed stripfrom the blank of Fig. '2. Fig. Sis a side View of a twisted barbedstrip from the blank of Fig. 1, and Fig. 9 is a side view of a twistedbarbed strip from the blank of Fig. 2.

I take a narrow flat blank strip, a, of the desired thickness, asrepresented in the section of Figs. 6 and 7, said strip being as wide astwo of the completed strips 1) and one barb, and slit said blank alongthe lines 0 (Z c by any suitable contrivance of slitting machinery,separating it into two strips b, each having short barb ribs f atintervals along one, edge, the ribs of one strip 1) being the metaltaken from the notches g of the other strip, the said ribs and notchesbeing longer or shorter according asI desire to make the ribs for asingle barb or for two barbs. I then take the separate strips b and slitthe barb ribs from its edge a suitable distance along the line It in anyapproved way, as by shearing them in the manner indicated in Fig. 4,from one end only for single barbs,and from both ends for two barbsto-one rib, and then bend the barbs outward, as shown in Figs. 6 and 7,which represent them in two different angles, and they may be otherwisemodified in this respect, and I also bend the barbs back into the'planeof the strips 1), either be fore or after bending them outwardly. Thebarbed strips thus made are to be twisted, as represented in Figs. 8 and9, like other fencing of like character.

It will be seen that the above-described method of making barbed fencingis exceedingly simple and cheap, and is accomplished without any wasteof material and by means of simple machinery, and the fencing itself issubstantial and durable.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

The method of making barbed metallic fencing-strips by slitting a blankstrip, a, along lines o d ethrough the middle portion to form twostrips, 1), having ribsf and notches g, by

cutting the ribs f of one strip corresponding to the notches g of theother strip, then slitting the ribs f along lines h coincident with 'theedge of the strips in the notches g and bending out said ribs f, thusforming projecting barbs, substantially as described.

In witness whereof I have hereunto signed .IAooB G. CARPENTER, A. P.THAYER.
